diagram as source code. The components of the block diagram 
represent program nodes such as For Loops, Case structures, and 
multiplication functions. The components are wired together to show 
the flow of data within the block diagram.

The outermost structure in this diagram is the While Loop. It continues 
to run until the power switch is turned off. The objects inside the loop 
include functions and subVIs that generate simulated data that is 
displayed on the historical trends and other objects on the front panel.

At this point, you do not need to understand all of the structures and 
objects completely. Chapters 9 through 16 of this manual describe in 
greater detail each element that appears in a VI.

BridgeVIEW Environment Project Menu

The BridgeVIEW system is comprised of the G programming language 
and a collection of software tools designed specifically for industrial 
automation applications. You can access these tools through the Project 
menu in your BridgeVIEW system. Table 2-1 provides a brief description 
of the items in the Project menu.
